Product Description

Industrial Silicon Metal Powder

Industrial Silicon Metal Powder

Characteristics:

Silicon metal powder is a silver-grey or dark-grey powder with a metallic luster. It has a high melting point, excellent heat resistance, high resistivity, and anti-oxidation properties. Often referred to as the "industrial monosodium glutamate," it is a crucial raw material for various high-tech industries.

Applications:

1. Used in the production of refractory materials and metallurgical applications due to its high temperature resistance, wear resistance, and oxidation resistance.


2. Base material for organic silicon products, such as silicon monomers, silicone oils, and silicone rubber preservatives, providing enhanced temperature resistance, electrical insulation, corrosion resistance, and waterproofing properties.


3. Utilized in the production of integrated circuits and electronics components, driving high-tech industries forward.


4. As an additive in the metallurgical casting industry to enhance the hardness of nonferrous alloys and silicon steel.


5. Widely used in refractories and powder metallurgy to improve thermostability, wear resistance, and inoxidizability of products.

Additional Applications:

1. Basic material for organosilicon polymer synthesis, producing silicon monomers, silicone oils, and silicon rubber preservatives.


2. Key component in the production of trichlorosilane and polysilicon for hi-tech fields.


3. Used in metallurgy and foundry industry as non-iron-based alloy additives and silicon steel alloying agents.


4. For the production of silica sol and in the electronics industry.

Common specifications include 40-120 mesh, 200 mesh, 325 mesh, 800 mesh, etc., with the ability to supply different particle size ranges based on customer needs.
